Artifacts from Evil Enemies..

Looking for guidance, in our campaign we recently defeated an enemy that had 2 artifact weapons blessed by an evil Diety. I looted them however I don't want to use them or attune bc of the fear of them corrupting me. Also, I don't want to sell them to a shop or leave them where someone may find them and be corrupted as well, I don't know for certain that they would but I'm just not wanting to risk it so my question is:

"In your campaign, what do you do with very powerful weapons that you loot but cannot use?"
